The 3 minute and 57 second clip offers intimate insight into not only Theodore's relationship with Samantha, but with his ex-wife Catherine, played by Rooney Mara.

Nominated for five Academy Awards including best picture, Her has already pulled at the heartstrings of viewers with its touching tale of a man (Joaquin Phoenix) who falls in love with a computer operating system (voiced by Scarlett Johansson).

However, new behind-the-scenes footage from Spike Jonze's futuristic love story focuses not on Theodore's and Samantha's virtual relationship, but on his failed marriage to Catherine, played by Rooney Mara.

"So, what was it like being married?" asks Johansson, as the classical soundtrack (William Butler and Owen Pallett also are nominated for best original score) moves viewers through scrolling images of personal artifacts from their past together, including a love note addressed to: "My other half."

"She came from a background where nothing was ever good enough. In our house it was just about trying stuff, being excited about things, that was liberating for her, it was exciting to see her grow. Both of us grew and changed together.

"I still find myself having conversations with her in my mind," laments Theodore sadly.

While most public attention has been centered on Samantha and Theo, the 3 minute and 57 second footage is a moving insight into Mara's character and adds even more emotional layers to Jonze's eclectic film.
